This application claims the benefit of U.S. Provisional Application Ser.No. 63/171,305, filed on Apr. 6, 2021; the disclosure of which isincorporated herein by reference.

TECHNICAL FIELD

This disclosure is directed to adjustable desks and tables. Moreparticularly, the disclosure is directed to an adjustable desk thatoperably engages an exercise machine. Specifically, the disclosure isdirected to an adjustable desk that is configured to expand, elevate,and tilt while mounted to a treadmill machine.

BACKGROUND

In current office settings, workers are experiencing more sedentarylifestyles throughout their workdays while sitting at a desk forprolonged hours. Such sedentary lifestyles may lead to negative impactson a worker's life such as increased pain and stress on the lower back(i.e., spinal disk degeneration), increased psychiatric distress such asanxiety, depression, fatigue, and/or low energy, and physical weightgain. To alleviate these issues, office settings are graduallyintroducing adjustable desks and tables for workers. These desks, whichare frequently called “standing desks” allow a worker to standperiodically throughout the workday rather than only sitting at a desk.Standing desks help address at least part of the worker's sedentarylifestyle issues. While known adjustable desks and tables provide aworker with the capability of standing periodically throughout theirworkday, the worker typically will still remain stationary and in placewhile working.

SUMMARY

The present inventor has recognized that there is a problem withproviding a conventional desk adjacent a cardiovascular machine. Whileworkers and/or users of exercise machines may provide a conventionaldesktop or tabletop to an exercise machine (e.g., treadmills, ellipticalmachines, etc.), these methods and techniques are rather dangerous whenusing the piece of exercise equipment (e.g., the desk or table maydisengage from the treadmill when walking or running on the treadmillcausing harm and/or injury to the user when operating the treadmill). Inaddition, these methods and techniques of providing conventional desktopand/or tabletops to exercise equipment fail to provide a comfortable andergonomic position for the user when the user is using the desk and/ortable and the exercise machine simultaneously (e.g., desk/table is tooshort for the user, the desk/table is disposed at an uncomfortableangle, etc.).

In the prior art, it is proposed that a treadmill or stationary bicycle,in some instances, be moved into a position adjacent a conventional deskor adjacent a standing desk. In other instances, a desk unit ispositioned next to a cardiovascular machine where the desk unit can bereached when a person is walking on a treadmill, for example, or whileriding a stationary bicycle. In yet other instances, a desk may beintegrated with a treadmill. The treadmill desk sold by NordicTrack®,for example, includes a desk that is engaged with a conventionaltreadmill. The treadmill is able to be pivoted between a generallyhorizontal exercise position where a worker is able to walk on it whileworking, and a generally vertical storage position where the worker cansit on a chair and still use the desk. The desk is able to be verticallyraised and lowered, and is pivotable about a vertical axis to allow thetreadmill to be moved between the exercise position and the storageposition. While this treadmill desk is versatile, it is a relativelyexpensive piece of equipment.

In sum, the current options and conventional devices in the market failto alleviate the issue of providing an adjustable desk on an exercisedevice in a safe, ergonomic, and cost-effective manner. With theseissues, the present inventor has recognized that a desk provided on acardiovascular equipment would be less dangerous and more ergonomic ifthe desk is sufficiently secured to the cardiovascular equipment and isselectively adjustable to provide an ergonomic position for the user.

As such, the thirdrelease knob 506 is disposed closer to first end 533A of the slot 533,and the fourth release knob 508 is disposed closer to the first end 553Aof the slot 553.

Once a desired angle is determined by a user, the handle 506C, 508C maybe reengage the outer surfaces 425, 455 of the first and second pivotbrackets 502, 504. To reengage the outer surfaces 425, 455 of the firstand second pivot brackets 502, 504 and maintain the first and secondadjustment members 310, 312 in the desired tilted position, the userapplies an opposing rotational force on each of the third and fourthrelease knobs 506, 508 in the clockwise direction until the handles506C, 508C of the third and fourth release knobs 506, 508 engage theouter surfaces 530, 550 of the first and second pivot brackets 502, 504.Such engagement compresses the first adjustment member 310 against thefirst pivot bracket 502 and compresses the second adjustment member 312against the second pivot plate 508 to prevent against rotationalmovement of the first and second adjustment members 310, 312.

In the illustrated embodiment, the top and bottom platforms 100, 200rotate and/or tilt collectively due to the configuration of the top andbottom platforms 100, 200 in the adjustable desk 10. In other words, thetop and bottom platform 100, 200 remain parallel with one another whenrotated and/or tilted at any capable angle. In addition, the associatedcomponents that make up the expansion assembly 300 remain parallel withthe top and bottom platform 100, 200 in the level and tilted positions.In the level position, the top and bottom platforms 100, 200 arecollectively parallel to the bottom portions 528, 548 of the first andsecond pivot brackets 502, 504. As illustrated in FIG. 21, the top andbottom platforms 100, 200 are collectively defined at an angle α that ismeasured relative to the bottom portions 528, 548 of the first andsecond pivot brackets 502, 504 in the tilted position. In one exemplaryembodiment, the angle α may be between the range of about 0 degrees toabout 90 degrees. In another exemplary embodiment, the angle α may bebetween the range of about 0 degrees to about −90 degrees. In the tiltedposition, the first and second stoppers 140, 240 of the top and bottomplatforms 100, 200 prevent items and/or objects from sliding off of thetop and bottom platforms 100, 200.

The capability of rotating and/or tilting the top and bottom platforms100, 200 is considered advantageous at least because this capabilityallows a user to tilt the first and second platforms 100, 200 dependingon what angle of tilt is most comfortable and/or ergonomic for the userwhen using the adjustable desk 10 on the treadmill 1. For example, auser may tilt the top and bottom platforms 100, 200 downwardly tocomplement the angle of tilt and/or incline the treadmill 1 is disposedat when the user is operating the treadmill at an inclined angle. Inaddition, the determination made by the user may be dependent on theheight of the user, the type of activity being used on the adjustabledesk 10 by the user, and other suitable determinations that areconsidered useful for making the adjustable desk 10 more comfortable andergonomic for the user.

As illustrated in FIGS. 22, 23, and 28, the first and second pivotbrackets 502, 504 may be oriented in a different arrangement when theadjustable desk 10 engages the treadmill 1.

The thread 874 is complementary to thethreading 847 provided on the lead nut apparatus 712 such that the leadscrew 714 is able to linearly transition the lead nut apparatus 712 andother components operably engaged to the lead nut apparatus 711 betweenthe front and rear ends 200A, 200B of the bottom platform 200 tovertically elevate the top portion 100 away from the bottom platform200. Such interaction between the lead nut apparatus 712 and the leadscrew 714 is described in more detail below.

The shaft 870 also includes a blanked portion 876 that extends from thethread 874 to the second end 870B of the shaft 870. The shaft 870 alsodefines a groove 878 that extends radially into the shaft 870 on theblanked portion 876. The groove 878 is disposed between the thread 874and the second end 870B of the shaft 870 and is closer to the second end870B of the shaft 870. The groove 878 is sized and configured to receiveand operably engage a flanged seal bearing 880 that is disposed in therear portion 226 of the wall 220 of the bottom platform 200. The flangedseal bearing 880 allows the shaft 870 to rotatably move on the flangedseal bearing 880 at the groove 878 when the adjustable desk 10 isassembled.

The lifting assembly 700 also includes a spring 718 that is disposedabout a portion of the shaft 870 of the lead screw 714 between the firstend 870A of the shaft 870 to a location between the first and secondends 870A, 870B of the shaft 870. The spring 718 defines a first end718A and an opposing second end 718B. Once the adjustable desk 10 isassembled, the first end 718A of the spring 718 is disposed at the frontend 200A of the bottom platform 200 and abuts the inner surface 238 ofthe wall 220 at the frontal portion 222, and the second end 718B of thespring 718 is disposed between the front and rear ends 200A, 200B of thebottom portion 200 and abuts the front end 840A of the main body 840 ofthe lead nut apparatus 712. In the illustrated embodiment, the spring718 is a compression spring that is biased to expand. When theadjustable desk 10 is assembled, the spring 718 provides assistance tothe lifting assembly 700 to help vertically elevate the top platform 100away from the bottom platform 200. In other words, the spring 718asserts a linear force against the lead screw apparatus 712 and thefront portion 222 of the wall 220 of the bottom portion 200 to help theuser vertically elevate the top platform 100 away from the bottomplatform 200.

The lifting assembly 700 of the adjustable desk 10 includes a collapsedposition (FIG. 2) and an elevated position (FIG. 19-21). In thecollapsed position, the central portion 122 of the top platform 100 ismeasured at a first distance D₁ relative to the central portion 222 ofthe bottom platform 200. As illustrated in FIG. 4, the lead nutapparatus 712 is disposed closer to the front end 200A of the bottomplatform 200 near the frontal portion 222. In the collapsed position,the left arm tube 708A directly contacts the second tab 330 of the firstsupport plate 302 and the right arm tube 708B directly contacts thesecond tab 350 of the second support plate 304 to define the limits ofthe collapsed position. Moreover, the spring 718 defines a first lengthL₁ measured from the first end 718A of the spring 718 to the second end718B of the spring 718 when the adjustable desk 10 is in the collapsedposition. As illustrated in FIG. 18, the first end 720A of the leftouter arm 702A is measured at a first distance E₁ from the second end730B of the left inner arm 704A when the adjustable desk 10 is in thecollapsed position. Similarly, the first end 740A of the right outer arm702B is measured at a first distance F₁ from the second end 750B of theright inner arm 704B when the adjustable desk 10 is in the collapsedposition.

In order to transition the lifting assembly 700 of the adjustable desk10 from the collapsed position to the elevated position, a user of theadjustable desk 10 must exert a force on the lifting adjustment knob716. Specifically, the user exerts a rotational force on the liftingadjustment knob 716 in the clockwise direction to vertically elevate thetop platform 100 away from the bottom platform 200. Upon rotation of thelifting adjustment knob 716, the lead screw 714 rotates along a fifthaxis of rotation X₅ defined along the shaft 870 of the lead screw 714that extends from the first end 870A of the shaft 870 to the second end870B of the shaft 870. The lead screw 714 freely rotates via the groove878 being disposed inside the flanged seal bearing 880 at the second end870B of the shaft 870. Such configuration allows a user to continuouslyrotate lead screw 714 to transition the lead screw apparatus 712. As thelead screw 714 rotates, the lead nut apparatus 712 transitions linearlytowards the rear end 200B of the bottom platform 200 and away from thefront end 200A of the bottom platform 200 via the complementaryconfiguration between the threading 847 of the lead nut apparatus 712and the thread 874 of the lead screw 714. As the lead nut apparatus 712transitions towards the rear end 200B of the bottom platform 200, eachof the left tube arm 708A, right tube arm 708B, left stabilizer 710A,and right stabilizer 710B transitions towards the rear end 200B of thebottom platform 200 given the associated components are operably engagedto the lead nut apparatus 712. In addition, the second ends 720B, 740Bof the left and right outer arms 702A, 702B transition with the lead nutapparatus 712 due to the left and right outer arms 702A, 702B beingoperably engaged with the left and right tube arms 708A, 708B.

As the lifting assembly 700 transitions from the collapsed position tothe elevated position, the lips 806, 826 of the left and rightstabilizers 710A, 7106 directly interface with and contact the centralportion 222 of the bottom platform 200 inside the first and second slots246, 248 and the central portions 322, 342 of the first and secondsupport plates 302, 304 to maintain the position of the lead nutapparatus 712 during transition. Specifically, the lip 806 of the leftstabilizer 710A interfaces with and contacts the central portion 222 ofthe bottom platform 200 inside the first slot 246 and an outer edge ofthe central portion 322 near the right end 302D of the first supportplate 302 to maintain the position of the lead nut apparatus 712 duringtransition. Similarly, the lip 826 of the right stabilizer 7106interfaces with and contacts the central portion 222 of the bottomplatform 200 inside the second slot 248 and an outer edge of the centralportion 342 near the left end 304C of the second support plate 304 tomaintain the position of the lead nut apparatus 712 during transition.

As the lead screw apparatus 712 transitions towards the rear end 200B ofthe bottom platform 200, the left outer and inner arms 702A, 704A andthe right outer and inner arms 702B, 704B collectively create ascissor-lifting mechanism to vertically elevate the top platform 100away from the bottom platform 200. As the second end 720B of the leftouter arm 702A transitions towards the rear end 200B of the bottomplatform 200, the second end 720B of the left outer arm 702A exerts alinearly force against the left inner arm 702B directed towards the rearend 200B of the bottom platform 200. The exerted force of the left outerarm 702A onto the left inner arm 704A is created via the fastener 760Aconnecting the left outer arm 702A with the left inner arm 704A. Withthis, any movement asserted on the left outer arm 702A via the lead nutapparatus 712 is communicated to the left inner arm 702B. Similarly, asthe second end 740B of the left outer arm 702B transitions towards therear end 200B of the bottom platform 200, the second end 740B of theright outer arm 702B exerts a linearly force against the right inner arm704B directed towards the rear end 200B of the bottom platform 200. Theexerted force of the right outer arm 702B onto the right inner arm 704Bis created via the fastener 762A connecting the right outer arm 702Bwith the right inner arm 704B. With this, any movement asserted on theright outer arm 702B via the lead nut apparatus 712 is communicated tothe right inner arm 704B.

To help prevent resistance while vertically elevating the top platform100 away from the bottom platform 200, the left and right bushings 706A,706B directly interface with and contact the inner surface 138 of thetop platform 100 to slideably move the top platform 100 away from thebottom platform 200. Specifically, the left bushing 706A interfaces withand contacts the inner surface 138 at the left end 100C of the topplatform 100 to slideably move the top platform 100 away from the bottomplatform 200. Similarly, the right bushing 706B interfaces with andcontacts the inner surface 138 at the right end 100D of the top platform100 to slideably move the top platform 100 away from the bottom platform200.

In the desired elevation position, the user ceases rotation of thelifting adjustment knob 716. As illustrated in FIGS. 15-17, the liftingassembly 700 of the adjustable desk 10 reaches its maximum elevatedposition. In the elevated position, the central portion 122 of the topplatform 100 is measured at a second distance D₂ relative to the centralportion 222 of the bottom platform 200; the second distance D₂ isgreater than the first distance D₁ in the collapsed position. Inaddition, the lead nut apparatus 712 is disposed closer to the rear end200A of the bottom platform 200 near the rear portion 224. In themaximum elevated position, the left arm tube 708A directly contacts thefirst tab 328 of the first support plate 302 and the right arm tube 708Bdirectly contacts the first tab 348 of the second support plate 304 todefine the limits of the maximum elevated position. Moreover, the spring718 defines a second length L₂ measured from the first end 718A of thespring 718 to the second end 718B of the spring 718 when the adjustabledesk 10 is in the elevated position. The second length L₂ of the spring718 in the elevated position is greater than the first length L₁ of thespring 718 in the collapsed position. Furthermore, the first end 720A ofthe left outer arm 702A is measured at a second distance E₂ from thesecond end 730B of the left inner arm 704A when the adjustable desk 10is in the elevated position. Similarly, the first end 740A of the rightouter arm 702B is measured at a second distance F₂ from the second end750B of the right inner arm 704B when the adjustable desk 10 is in theelevated position. The second distance E₂ is less than the firstdistance E₁, and the second distance F₂ is less than the first distanceF₁.

In addition, the top platform 100 may be vertically elevated at anysuitable distance away from the bottom platform 200 between thecollapsed position (as illustrated in FIG. 1) and the maximum elevatedposition (as illustrated in FIGS. 15-17) due to the configurationbetween the lead nut apparatus 712, the lead screw 714, and the spring718. An exemplary range in which the top platform 100 may be disposedfrom the bottom platform 200 is from about 3.75 inches up to about 10inches In addition, the lead screw apparatus 712 may be disposed at anysuitable location between the first tabs 328, 348 of the first andsecond support plates 302, 304 and the second tabs 330, 350 of the firstand second support plates 302, 304 as determined by the user. Thedetermination of elevation for the top platform 100 made by the user maybe dependent on the height of the user, the type of activity being usedon the adjustable desk by the user, and other suitable determinationsthat are considered useful for making the adjustable desk morecomfortable and ergonomic for the user.

Various inventive concepts may be embodied as one or more methods, ofwhich an example has been provided. The acts performed as part of themethod may be ordered in any suitable way. Accordingly, embodiments maybe constructed in which acts are performed in an order different thanillustrated, which may include performing some acts simultaneously, eventhough shown as sequential acts in illustrative embodiments.

While various inventive embodiments have been described and illustratedherein, those of ordinary skill in the art will readily envision avariety of other means and/or structures for performing the functionand/or obtaining the results and/or one or more of the advantagesdescribed herein, and each of such variations and/or modifications isdeemed to be within the scope of the inventive embodiments describedherein. More generally, those skilled in the art will readily appreciatethat all parameters, dimensions, materials, and configurations describedherein are meant to be exemplary and that the actual parameters,dimensions, materials, and/or configurations will depend upon thespecific application or applications for which the inventive teachingsis/are used. Those skilled in the art will recognize, or be able toascertain using no more than routine experimentation, many equivalentsto the specific inventive embodiments described herein. It is,therefore, to be understood that the foregoing embodiments are presentedby way of example only and that, within the scope of the appended claimsand equivalents thereto, inventive embodiments may be practicedotherwise than as specifically described and claimed. Inventiveembodiments of the present disclosure are directed to each individualfeature, system, article, material, kit, and/or method described herein.In addition, any combination of two or more such features, systems,articles, materials, kits, and/or methods, if such features, systems,articles, materials, kits, and/or methods are not mutually inconsistent,is included within the inventive scope of the present disclosure.

The articles “a” and “an,” as used herein in the specification and inthe claims, unless clearly indicated to the contrary, should beunderstood to mean “at least one.” The phrase “and/or,” as used hereinin the specification and in the claims (if at all), should be understoodto mean “either or both” of the elements so conjoined, i.e., elementsthat are conjunctively present in some cases and disjunctively presentin other cases. Multiple elements listed with “and/or” should beconstrued in the same fashion, i.e., “one or more” of the elements soconjoined. Other elements may optionally be present other than theelements specifically identified by the “and/or” clause, whether relatedor unrelated to those elements specifically identified. Thus, as anon-limiting example, a reference to “A and/or B”, when used inconjunction with open-ended language such as “comprising” can refer, inone embodiment, to A only (optionally including elements other than B);in another embodiment, to B only (optionally including elements otherthan A); in yet another embodiment, to both A and B (optionallyincluding other elements); etc. As used herein in the specification andin the claims, “or” should be understood to have the same meaning as“and/or” as defined above. For example, when separating items in a list,“or” or “and/or” shall be interpreted as being inclusive, i.e., theinclusion of at least one, but also including more than one, of a numberor list of elements, and, optionally, additional unlisted items. Onlyterms clearly indicated to the contrary, such as “only one of” or“exactly one of,” or, when used in the claims, “consisting of,” willrefer to the inclusion of exactly one element of a number or list ofelements. In general, the term “or” as used herein shall only beinterpreted as indicating exclusive alternatives (i.e. “one or the otherbut not both”) when preceded by terms of exclusivity, such as “either,”“one of,” “only one of,” or “exactly one of.” “Consisting essentiallyof,” when used in the claims, shall have its ordinary meaning as used inthe field of patent law.

As used herein in the specification and in the claims, the phrase “atleast one,” in reference to a list of one or more elements, should beunderstood to mean at least one element selected from any one or more ofthe elements in the list of elements, but not necessarily including atleast one of each and every element specifically listed within the listof elements and not excluding any combinations of elements in the listof elements. This definition also allows that elements may optionally bepresent other than the elements specifically identified within the listof elements to which the phrase “at least one” refers, whether relatedor unrelated to those elements specifically identified. Thus, as anon-limiting example, “at least one of A and B” (or, equivalently, “atleast one of A or B,” or, equivalently “at least one of A and/or B”) canrefer, in one embodiment, to at least one, optionally including morethan one, A, with no B present (and optionally including elements otherthan B); in another embodiment, to at least one, optionally includingmore than one, B, with no A present (and optionally including elementsother than A); in yet another embodiment, to at least one, optionallyincluding more than one, A, and at least one, optionally including morethan one, B (and optionally including other elements); etc.

When a feature or element is herein referred to as being “on” anotherfeature or element, it can be directly on the other feature or elementor intervening features and/or elements may also be present. Incontrast, when a feature or element is referred to as being “directlyon” another feature or element, there are no intervening features orelements present. It will also be understood that, when a feature orelement is referred to as being “connected”, “attached” or “coupled” toanother feature or element, it can be directly connected, attached orcoupled to the other feature or element or intervening features orelements may be present. In contrast, when a feature or element isreferred to as being “directly connected”, “directly attached” or“directly coupled” to another feature or element, there are nointervening features or elements present. Although described or shownwith respect to one embodiment, the features and elements so describedor shown can apply to other embodiments. It will also be appreciated bythose of skill in the art that references to a structure or feature thatis disposed “adjacent” another feature may have portions that overlap orunderlie the adjacent feature.

Spatially relative terms, such as “under”, “below”, “lower”, “over”,“upper”, “above”, “behind”, “in front of”, and the like, may be usedherein for ease of description to describe one element or feature'srelationship to another element(s) or feature(s) as illustrated in thefigures. It will be understood that the spatially relative terms areintended to encompass different orientations of the device in use oroperation in addition to the orientation depicted in the figures. Forexample, if a device in the figures is inverted, elements described as“under” or “beneath” other elements or features would then be oriented“over” the other elements or features. Thus, the exemplary term “under”can encompass both an orientation of over and under. The device may beotherwise oriented (rotated 90 degrees or at other orientations) and thespatially relative descriptors used herein interpreted accordingly.Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”,“lateral”, “transverse”, “longitudinal”, and the like are used hereinfor the purpose of explanation only unless specifically indicatedotherwise.

Although the terms “first” and “second” may be used herein to describevarious features/elements, these features/elements should not be limitedby these terms, unless the context indicates otherwise. These terms maybe used to distinguish one feature/element from another feature/element.Thus, a first feature/element discussed herein could be termed a secondfeature/element, and similarly, a second feature/element discussedherein could be termed a first feature/element without departing fromthe teachings of the present invention.

An embodiment is an implementation or example of the present disclosure.Reference in the specification to “an embodiment,” “one embodiment,”“some embodiments,” “one particular embodiment,” “an exemplaryembodiment,” or “other embodiments,” or the like, means that aparticular feature, structure, or characteristic described in connectionwith the embodiments is included in at least some embodiments, but notnecessarily all embodiments, of the invention. The various appearances“an embodiment,” “one embodiment,” “some embodiments,” “one particularembodiment,” “an exemplary embodiment,” or “other embodiments,” or thelike, are not necessarily all referring to the same embodiments.

If this specification states a component, feature, structure, orcharacteristic “may”, “might”, or “could” be included, that particularcomponent, feature, structure, or characteristic is not required to beincluded. If the specification or claim refers to “a” or “an” element,that does not mean there is only one of the element. If thespecification or claims refer to “an additional” element, that does notpreclude there being more than one of the additional element.

As used herein in the specification and claims, including as used in theexamples and unless otherwise expressly specified, all numbers may beread as if prefaced by the word “about” or “approximately,” even if theterm does not expressly appear. The phrase “about” or “approximately”may be used when describing magnitude and/or position to indicate thatthe value and/or position described is within a reasonable expectedrange of values and/or positions. For example, a numeric value may havea value that is +/−0.1% of the stated value (or range of values), +/−1%of the stated value (or range of values), +/−2% of the stated value (orrange of values), +/−5% of the stated value (or range of values), +/−10%of the stated value (or range of values), etc. Any numerical rangerecited herein is intended to include all sub-ranges subsumed therein.

Additionally, the method of performing the present disclosure may occurin a sequence different than those described herein. Accordingly, nosequence of the method should be read as a limitation unless explicitlystated. It is recognizable that performing some of the steps of themethod in a different order could achieve a similar result.

In the claims, as well as in the specification above, all transitionalphrases such as “comprising,” “including,” “carrying,” “having,”“containing,” “involving,” “holding,” “composed of,” and the like are tobe understood to be open-ended, i.e., to mean including but not limitedto. Only the transitional phrases “consisting of” and “consistingessentially of” shall be closed or semi-closed transitional phrases,respectively.

In the foregoing description, certain terms have been used for brevity,clearness, and understanding. No unnecessary limitations are to beimplied therefrom beyond the requirement of the prior art because suchterms are used for descriptive purposes and are intended to be broadlyconstrued.

Moreover, the description and illustration of various embodiments of thedisclosure are examples and the disclosure is not limited to the exactdetails shown or described.
